Abstract
Interleukin-11 (IL-11) is a versatile cytokine that modulates cellular differentiation and proliferation in various cell types and tissues. In this study, IL-11 gene from goldfish (Carassius auratus L.) has been identified and characterized. Goldfish IL-11 (gfIL-11) has an open reading frame (ORF) that spans 591 base pairs (bp). The ORF encodes a precursor protein consisting of 196 amino acids (aa), which includes a 26 aa signal peptide and a conserved domain belonging to the IL-11 superfamily. Based on phylogenetic analysis, gfIL-11 was found to be closely related to other IL-11 homologues identified in various fish species. The gfIL-11 transcript exhibited varied expression levels across all the analyzed tissues, with the highest expression observed in the gill and spleen. Treatment of goldfish head kidney leukocytes (HKLs) with LPS and live Aeromonas hydrophila, increased gfIL-11 mRNA expression level. Recombinant gfIL-11 protein (rgIL-11) induced a dose-dependent production of TNF-α and IFNγ from goldfish HKLs. Furthermore, the administration of rgIL-11 to goldfish HKLs triggered an increase in the expression of various transcription factors such as MafB, cJun, GATA2, and Egr1, which play a vital role in the differentiation of myeloid precursors into macrophages and monocytes. Our findings provide evidence that IL-11 is a crucial cytokine that promotes cell proliferation, immune response, and differentiation across various hematopoietic lineages and stages of goldfish.

[PMID: 36586293 PMCID: PMC9811199 DOI: 10.1016/j.psj.2022.102399] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 10/24/2022] [Accepted: 12/05/2022] [Indexed: 12/13/2022] Open
Abstract
Interleukin-1 receptor type 2 (IL1R2) is a decoy receptor for exogenous IL-1. However, its functional role in chicken immunity is poorly understood. Herein, chicken IL-1R2 (chIL-1R2) was identified and functionally characterized in vivo and in vitro. The chIL-1R2 coding sequence includes 1,236 nucleotides encoding 412 amino acids, is highly conserved, and has a close relationship with its mammalian counterpart. Its extracellular region has three Ig-like domains but no TIR domain for intracellular signaling. Using ELISA, the recombinant chIL-1R2 protein was demonstrated to specifically bind to the chicken IL-1β. ChIL-1R2 mRNA expression was shown to be higher in the spleen, lung, kidney, small intestine, and liver. The expression of chIL-1R2 and chIL-1R1 was significantly upregulated in DF-1 cells treated with poly (I:C), but significantly downregulated in the presence of NF-κB, JNK, and MEK inhibitors, indicating that the NF-κB, JNK, and MEK signaling pathways are required for the transcriptional regulation of chIL-1R1 and chIL-1R2 expression. It is worth noting that while the p30 MAPK pathway was required for chIL-1R1 expression, it was not required for chIL-1R2 expression. Furthermore, chIL-1R2 expression increased as early as day 1, and then significantly decreased until day 3, while chIL-1R1 was dramatically upregulated in four organs of chickens infected with the highly pathogenic avian influenza virus (HPAIV). These findings indicate that chIL-1R1 and chIL-1R2 may play a crucial in innate and adaptive immune responses toward HPAIV infection. In summary the present study showed that chIL-1R2 binds to chIL-1β antibody. ChIL-1R2 expression can be induced by a viral infection, and may be regulated through NF-κB/JNK/MEK-mediated signaling pathways.

Abstract
Interleukin (IL)-11 is a multifunctional cytokine belonging to the IL-6 family, which plays essential roles in immune response. However, much less is known about the immunological functions of IL-11 in teleost. In this study, we investigated the immune properties of a teleost IL-11 homologue (CsIL-11) from tongue sole Cynoglossus semilaevis. CsIL-11 possesses four conserved α-helices and conserved CsIL-11 receptor binding residues L86 and R187, and shares 23.3%-80.1% identities with other IL-11 homologues. CsIL-11 expression was constitutive in tissues, with most abundant in blood and least abundant in spleen, and upregulated by bacterial challenge in blood, spleen, and head kidney. Recombinant CsIL-11 (rCsIL-11) in the native form of monomer, could bind to peripheral blood leukocytes (PBLs) membrane and enhance the activation and phagocytosis of PBLs. When administered in vivo, rCsIL-11 could markedly promote the host to defend against microbial infection. Overall, our findings show that CsIL-11 plays a pivotal role in regulating PBLs phagocytosis and antibacterial immunity.

Identification and expression analysis of MicroRNAs in chicken spleen in a corticosterone-induced stress model. Res Vet Sci 2021; 136:287-296. [PMID: 33740563 DOI: 10.1016/j.rvsc.2021.02.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 11/13/2020] [Accepted: 02/26/2021] [Indexed: 01/22/2023]
Abstract
For investigating the effects of stress on the immune response of chickens, we established a corticosterone (CORT)-induced stress model by exogenous intake of CORT. Control group was fed with a basal diet and the stress model group was fed with a 30 mg/Kg CORT-treated diet in ad libitum conditions for 7 days. Then, we used RNA-seq technology to identify the expression pattern of miRNAs, target genes, and relevant pathways in chicken spleen. Results showed that 71 differentially expressed miRNAs (DEMs) were determined, 9 of which were significantly differentially expressed miRNAs (SDEMs), and 241 target genes of DEMs were predicted. GO annotation and KEGG pathway analysis were carried out to understand the role of the DEMs. Out of 287 significantly enriched GO terms, 37 were stress- or immune-related, such as response to light stimulus, detection of oxidative stress, and immune response in mucosal-associated lymphoid tissue. Out of 85 KEGG pathways, 8 were related to stress or immunity, such as cytokine-cytokine receptor interaction, JAK-STAT signaling pathway, and RLR signaling pathway. We then constructed the interaction networks between target genes from immune-related pathways and their DEMs. The analysis results suggested that some DEMs (gga-miR-17 family, gga-miR-15/16 family, gga-miR-2954 and gga-miR-34b-5p) and target genes (SIKE1, CX3CL1, IL11Ra, PIGR, and CDKN1A) were core miRNAs and genes. This study revealed the dynamic miRNA transcriptome, target genes and related pathways in chicken spleen under CORT-induced stress model, which provided a basis for studying the molecular mechanism of stress affecting immune function.

Abstract
The study aimed to monitor parasite and host gene expression during the early stages of Eimeria tenella infection of chicken cells using dual RNA-Seq analysis. For this, we used chicken macrophage-like cell line HD11 cultures infected in vitro with purified E. tenella sporozoites. Cultures were harvested between 2 and 72 h post-infection and mRNA was extracted and sequenced. Dual RNA-Seq analysis showed clear patterns of altered expression for both parasite and host genes during infection. For example, genes in the chicken immune system showed upregulation early (2–4 h), a strong downregulation of genes across the immune system at 24 h and a repetition of early patterns at 72 h, indicating that invasion by a second generation of parasites was occurring. The observed downregulation may be due to immune self-regulation or to immune evasive mechanisms exerted by E. tenella. Results also suggested pathogen recognition receptors involved in E. tenella innate recognition, MRC2, TLR15 and NLRC5 and showed distinct chemokine and cytokine induction patterns. Moreover, the expression of several functional categories of Eimeria genes, such as rhoptry kinase genes and microneme genes, were also examined, showing distinctive differences which were expressed in sporozoites and merozoites.

Abstract
Redox biology is a very quickly developing area of modern biological sciences, and roles of redox homeostasis in health and disease have recently received tremendous attention. There are a range of redox pairs in the cells/tissues responsible for redox homeostasis maintenance/regulation. In general, all redox elements are interconnected and regulated by various means, including antioxidant and vitagene networks. The redox status is responsible for maintenance of cell signaling and cell stress adaptation. Physiological roles of redox homeostasis maintenance in avian species, including poultry, have received limited attention and are poorly characterized. However, for the last 5 years, this topic attracted much attention, and a range of publications covered some related aspects. In fact, transcription factor Nrf2 was shown to be a master regulator of antioxidant defenses via activation of various vitagenes and other protective molecules to maintain redox homeostasis in cells/tissues. It was shown that Nrf2 is closely related to another transcription factor, namely, NF-κB, responsible for control of inflammation; however, its roles in poultry have not yet been characterized. Therefore, the aim of this review is to describe a current view on NF-κB functioning in poultry with a specific emphasis to its nutritional modulation under various stress conditions. In particular, on the one hand, it has been shown that, in many stress conditions in poultry, NF-κB activation can lead to increased synthesis of proinflammatory cytokines leading to systemic inflammation. On the other hand, there are a range of nutrients/supplements that can downregulate NF-κB and decrease the negative consequences of stress-related disturbances in redox homeostasis. In general, vitagene-NF-κB interactions in relation to redox balance homeostasis, immunity, and gut health in poultry production await further research.

Abstract
1. Leukocyte immunoglobulin-like receptor A5 (LILRA5) is a key molecule that regulates the immune system. However, the LILRA5 gene has not been characterised in avian species, including chickens. The present study aimed to identify and functionally characterise LILRA5 identified from two genetically disparate chicken lines, viz., Marek's disease (MD)-resistant (R) line 6.3 and MD-susceptible (S) line 7.2. 2. Multiple sequence alignment and phylogenetic analyses confirmed that the identity and similarity homologies of amino acids of LILRA5 in chicken lines 6.3 and 7.2 ranged between 93% and 93.7%, whereas those between chicken and mammals ranged between 20.9% and 43.7% and 21.1% to 43.9%, respectively. The newly cloned LILRA5 from chicken lines 6.3 and 7.2 revealed high conservation and a close relationship with other known mammalian LILRA5 proteins. 3. The results indicated that LILRA5 from chicken lines 6.3 and 7.2 was associated with phosphorylation of Src kinases and protein tyrosine phosphatase non-receptor type 11 (SHP2), which play a regulatory role in immune functions. Moreover, the results demonstrated that LILRA5 in these lines was associated with the activation of major histocompatibility complex (MHC) class I and β2-microglobulin and induced the expression of the transporter associated with antigen processing. In addition, LILRA5 in both chicken lines activated and induced Janus kinase (JAK)-signal transducer and the activator of transcription (STAT), nuclear factor kappa B (NF-κB), phosphoinositide-3-kinase (PI3K)/protein kinase B (AKT) and the extracellular signal-regulated kinase (ERK)1/2 signalling pathways; toll-like receptors; and Th1-, Th2-, and Th17- cytokines. 4. The data suggested that LILRA5 has innate immune receptors essential for macrophage immune response and provide novel insights into the regulation of immunity and immunopathology.

Abstract
Interleukins (ILs) regulate cell surface antigens known as activation markers, which have distinct functional roles. However, the regulation of major histocompatibility complex (MHC) class I, MHC class II, and related genes by cytokines in chickens is not well understood. In the present study, we evaluated the influence of certain recently discovered chicken interleukins-i.e., IL-11, IL-12B, IL-17A, IL-17B, IL-26, and IL-34-on the expression and regulation of genes related to MHC class I, MHC class II, and the associated proteins in an HD11 chicken macrophage cell line. We used quantitative reverse transcription polymerase chain reaction (qRT-PCR), immunocytochemical, and flow cytometric analyses to assess dose- and time-dependent expression in the HD11 cell line and found that the ILs induced MHC class I, MHC class II, and associated protein. As NF-κB is actively involved in cell activation and is constitutively activated in many immune cells, we also determined whether NF-κB regulates MHC class I, MHC class II, and related gene expression in the HD11 cell line. The NF-κB inhibitor sulfasalazine (Sz) dose-dependently inhibited MHC class I and MHC class II in the HD11 cell line. Sz also downregulated the expression of MHC class I, MHC class II, and the associated proteins in the IL-induced HD11 cell line. The expression of MHC class I, MHC class II, and associated genes was accompanied by the Sz-sensitive degradation of the p65 (RelA) and p50 subunits of NF-κB and IκBα. Our results indicate that the different effects of each IL on the expression of genes related to MHC class I, MHC class II, and the associated proteins are involved with the regulation of the dose and duration of antigenic peptide presentation and, thus, also influence Th1, Th2, and Th17 production.

Abstract
The chicken bursa of Fabricius is a primary lymphoid tissue important for B-cell development. Our long-term goal is to understand the role of bursal microenvironment in an early B-cell differentiation event initiating repertoire development through immunoglobulin gene conversion in the chick embryo. We hypothesize that early bursal B-cell differentiation is guided by signals through cytokine receptors. Our theory is based on previous evidence for expression of the receptor tyrosine kinase superfamily members and interleukin receptors in unseparated populations of bursal B-cells and bursal tissue. Knowledge of the expressed genes that are responsible for B-cell differentiation is a prerequisite for understanding the bursal microenvironment's function. This project uses transcriptomic analysis to evaluate gene expression across early B-cell development. RNA-seq was performed with total RNA isolated from bursal B-cells at embryonic day (ED) 16 and ED 19 (n = 3). Approximately 90 million high-quality clean reads were obtained from the cDNA libraries. The analysis revealed differentially expressed genes involved in the Jak-STAT pathway, Wnt signaling pathway, MAPK signaling pathway, metabolic pathways including tyrosine metabolism, Toll-like receptor signaling pathway, and cell-adhesion molecules. The genes predicted to encode surface receptors, signal transduction proteins, and transcription factors identified in this study represent gene candidates for controlling B-cell development in response to differentiation factors in the bursal microenvironment.

[PMID: 31502734 DOI: 10.1002/cbin.11236] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Accepted: 09/08/2019] [Indexed: 01/24/2023]
Abstract
The purpose of this study was to explore the potential function of interleukin-11 (IL-11) in the pathogenesis of primary Sjögren's syndrome (pSS) patients. Real-time polymerase chain reaction was performed to examine IL-11 expression in the labial glands of 30 pSS patients and 30 healthy controls. Immunohistochemistry was conducted to assess the distribution of IL-ll-positive cells in labial glands. The human salivary gland (HSG) cell line was used to study the effects of IL-11 on gland epithelial cells in vitro. Cell viability and cell proliferation were examined by CCK-8 kit and EdU assay, respectively. The population of apoptotic cells was detected in flow cytometry followed by Annexin V/PI and Hoechst staining. We found that the expression levels of IL-11 were remarkably decreased in pSS labial glands and were positively correlated with C-reactive protein levels and negatively correlated with rheumatoid factor levels. Fewer numbers of glandular epithelial cells were observed to be positively stained with IL-11 antibody in labial glands from pSS patients than those in healthy control patients. After IL-11 treatment, the viability and proliferation of HSG cells were significantly higher than those in the control group. The total apoptotic and necrotic rates of HSG cells in the group after IL-11 treatment were significantly lower. In conclusion, the results indicated that IL-11 promoted viability and proliferation and inhibited apoptotic and necrotic rates of glandular epithelial cells. In pSS, downregulated IL-11 might contribute to the apoptosis of salivary gland epithelial cells. However, it might be a potential target to alleviate the pathological atrophy of glandular epithelial cells in pSS patients.
